two large, thin metal plates are parallel and close to each other. On their inner faces, the plates have excess surface charge densities of opposite signs and magnitude 8.31 × 10-22 C/m2. What is the magnitude of the electric field at points (a) to the left of the plates, (b) to the right of them, and (c) between them?

A thin, circular disk of radius R = 45 cm is oriented in the yz-plane with its center as the origin. The disk carries a total charge Q = 6.0 μC distributed uniformly over its surface. Calculate the magnitude of the electric field due to the disk at the point x = 12 cm along the x-axis.

In the figure particle 1 (of charge +7.58 mC), particle 2 (of charge +7.58 mC), and particle 3 (of charge Q) form an equilateral triangle o edge length a. For what value of Q (both sign and magnitude) does the net electric field produced by the particles at the center of the triangle vanish? Number i Units C-m

In the figure a uniform, upward electric field of magnitude 1.60 × 103 N/C has been set up between two horizontal plates by charging the lower plate positively and the upper plate negatively. The plates have length L = 17.0 cm and separation d = 1.70 cm. An electron is then shot between the plates from the left edge of the lower plate. The initial velocity of the electron makes an angle 0 = 45.0° with the lower plate and has a magnitude of 6.40 × 105 m/s. (a) Will the electron strike one of the plates? (b) If so, which plate, top or bottom? (c) How far horizontally from the left edge will the electron strike? ↑E 5%8 (a) (b) (c) Number Mr Units <
